Abstract

L'invention porte sur un système de joint étanche à l'air pour un ensemble d'aubes de rotor de turbine à gaz, lequel système comprend un substrat. Une couche intermédiaire céramique facultative peut être disposée sur un revêtement adhésif facultatif déposé sur le substrat. Une couche de revêtement formant barrière thermique résistant à l'érosion (E-TBC) est disposée sur la couche intermédiaire céramique (si présente) ou sur le revêtement adhésif, ou sur le substrat. Une couche abradable est disposée sur la couche de revêtement formant barrière thermique résistante à l'érosion (E-TBC).
